Specification of Letters Patent. patentqgdl pl y 23 1 2 Application filed. February 5,1920. Serial No. 356,387.

To all whom it may OOH-062%.

Be it known that I, VILLIAM F. KrEsnL, J r., a citizen of the United States, residing at Altoona, in the county of Blair, State of Pennsylvania, have invented certain new and useful Improvements in Locomotives, of which the following is a specification.

The present invention relates to locomotives and more particularly to the connec tion between the frames or units of an articulated locomotive.

The principal objects of the invention are to provide an improved pivotal conneetlon between the adjacent ends of the frames or units of an articulated locomotive; and to provide animproved construction of the swinging unit of such a locomotive, whereby the pivotal connection between the frames may be simplified and located so as to be more accessible than heretofore.

Tn locomotives of the articulated type comprising two engines or units, each having 8 driving wheels, heretofore it has been difficult if not impossible to locate the pivot between the units where it theoretically belongs. The best that can be done is to locate the same considerably in rear of the front frame, that is, inside of the saddle of the rear engine. Theoretically the location of the pivot point is determined by the intersection of the center lines of the front and rear units. At present because the pivotal point is located well in rear of the front frame, the structure for connecting the units comprises a triangular or three point connecting link, which has a vertical pin connection at one apex with the rear unit and two hearings on a horizontal shaft attached to the rear end of the front frame.

According to the present invention the second and fourth pairs of wheels or the fourth pair of wheels on the front unit. have no flanges, while the first and fourth pairs or all the pairs of the rear unit have flanges. As a result of this construction it is possible to locate the pivot connectingthe frames where it theoretically belongs, as

said pivot comes in front of the rear saddle.

Other objects and features of novelty will be apparent from the description taken in connection with the drawings, in which- Figure 1 is atop plan view of a locomotive, more or less diagrammatic, illustrating the frames and the pivotal connection constructed in accordancewith the present invention. .The outline of the boiler is shown in dot and dash lines;

Flgure 2 is a side elevation of the parts shown in Fig. 1;

F lgure 3 is a top plan view to a large:- scale of the universal pivotal connection between the frames, parts of the saddle of the rear frame being shown in section, and

Figure 4 is a sectional elevation taken substantially on line 1-4 of Fig. 3.

Referring to the drawings it will be seen that the present invention is illustrated in connection with a-locomotive having two frames or units, the rear frame at its forward end being connected by means of 11 pivotal joint to the rear end of the forward frame, said joint being in front of the rear saddle. As shown, the forward frame coinprises the side bars 10 and 11 joined at their front ends to the saddle 12 of the front engine, the cylinders being shown at 13 and 14:. At the rear ends of the bars 10 and 11 is a transverse brace or cross member 15.

The rearv frame may comprise the side members 16 and 17 joined at their forward ends to the saddle 18 of the rear engine, the cylinders of this engine being shown at 19 and 20. The locomotive boiler is rigidly connected with the rear frame in any suitable manner, one of the connections being shown at 21. The front frame is adapted to swing relative to the boiler, a suitable sliding support as at 22 being provided.

The unit or engine which is adapted to swing relative to the boiler, that is in the present instance the front unit, does not have flanges on all the driving wheels. As shown, the first and third pairs of driving wheels 1O have the usual flanges while the second and fourth pairs 10 have no flanges. The rear unit which is rigid with the boiler is shown as having flanged driving wheels 16 on the first and fourth pairs, while the flanges are omitted from the second and toward the other frame.

stead of inside said saddle as is the case where all the wheels of the front unit have flanges. Because of this location of the pivot it is possible to provide a much more simplified and more accessible connection between the units. From an inspection of Figures 1 and 2, it will be seen that the pivot connecting the units is at a distance from the axis of the adjacent drivers approximately equal to that of the radius of said drivers. Of course, the exact location of the pivot will vary with the size and number of drivers in the unit, but its location may be approximately defined as stated above.

According to the present invention one of the adjacent ends of the frames is provided with an extension which co-operates with arms on the other frame to support the universal joint or connection securing the! frames together. In the form of the invention shown the saddle 18 of the rear engine is provided with an extension 23 projecting This extension is formed with a vertical aperture 24 with a shoulder 25 at the bottom thereof. Preferably this aperture is circular. A pair of blocks 26 and 27 are disposed in the aperture 24:, the lower peripheral edge of the lower block being formed with a rab-betted seat 28 resting on the shoulder 25. The top and bottom surfaces of the blocks are flush with the corresponding surfaces of the extension 23. In order to hold the blocks in position and together suitable bolts 29 are provided.

The blocks 26 and 2? taken together have their interior surfaces shaped to form a substantially spherical seat 30, and a substantially spherical member 31 is carried on this seat.

The cross member 15 of the front frame is provided with a pair of spaced arms 32 and 33 straddling the extension 23. A pin 34 extends through the arms and the spherical member 31, suitable bushings 35 and 36 being provided in the arms for the pin, if desired. The pin is held against longitudinal movement and to this end is provided with a head 37 at its lower end which prevents movement in one direction, that is, upward. Movement in the downward direction is preventd by the bolt 38 extending transversely to the pin and bearing against the lower surface of the head 37. In order to permit slight vertical rocking movements of the frames the distance between the adj acent faces ofthe arms 32 and 33 is slightly greater than the height of the extension 23. For thepurpose of lubricating the bearings, the pin 34 is provided with an axial hole 39 extending downward from its upper end to a point below the upper surface of the extension 23. At its upper end this axial hole is enlarged to provide a. cavity for a lubricant carrying packing or other material.

wrap/1e 40. In the plane substantially between the upper surface of the extension 23 and the lower surface of the arm 32 the pin is formed with. the radially extending oil ducts 11 whereby the lubricant is carried to the bearing surfaces between the pin and the spheri cal member and also between the spherical member and its seat.

In operation the front frame may swing in a horizontal direction considerably with respect to the rear frame. In this movement the pin 34 in the arms and the spherical. member, constitutes the pivot. For rocking movements in any other direction the spherical member 31 carried by the pin moves in its seat in the blocks 26 and 27. Furthermore because the flanges are omitted from the fourth pair of whee-ls of the front unit, the

pivotal connect-ion between the frames may be located in front of the rear frame and secured directly thereto, thereby affording a stronger, simpler and more connection.

Although an embodiment of the invention has been described in detail it is to be understood that the invention is not thus limited, but includes modifications and changes which come within the scope of the appended claims.
